Yes
The earthquakes in the san andrais fault line are one of the most dangerous.
The last 2. They both are correct. I hope this helps.
Answer:
it will take 
to reach its final rotating speed
Explanation:
Let initially the turntable is at rest
So its initial angular velocity will be 
Let the turn table is rotating with an angular acceleration 
According to first equation of motion
We know that 
, here 
So
So it will take to reach its final rotating speed
Part a can be solve using the equation of trajectory:
Y = x tana + (g*x^2)/ [2(V0^2)*(cos a)^2]
Where y is the height
X is the length
G is the acceleration due to gravity
Vo Is the initail velocity
a is the angle of trajectory
1.2 = 1.35 tan(0) +
(9.81*1.35^2)/ [2(V0^2)*(cos 0)^2]
Solve for V0 = 2.729 m/s
b. can be solve using the formula
v = sqrt(2gy)
= sqrt ( 2*1.2*9.81)
= 4.852 m/s going
down ( 0 degree from the horizontal)
